AIM A tissue-engineered periodontal ligament (PDL) around implants would represent an important new therapeutic tool to replace lost teeth. The PDL is the key to tooth anchoring; it connects tooth root and alveolar bone, and it sustains bone formation. MATERIALS AND METHODS Cells were isolated from PDL and cultured in a bioreactor on titanium pins. After the formation of multiple cellular lay...

Current evidence suggests that pigs were first domesticated in Eastern Anatolia during the ninth millennium cal BC before dispersing into Europe with Early Neolithic farmers from the beginning of the seventh millennium. Recent ancient DNA (aDNA) research also indicates the incorporation of European wild boar into domestic stock during the Neolithization process. In order to establish the timing...

  Objective: Microbial plaque is among the main etiologies of periodontal disease, and tooth brushing with toothpaste is the most commonly used method of plaque control. This study aimed to compare the efficacy of tooth brushing with and without three different dentifrices.   Methods: Thirty dental students were randomly selected to participate in this clinical trial and were asked to refrain f...

There is an ever increasing concern for dentofacial esthetics in adult population. The primary motivating factor for seeking orthodontic treatment is dental appearance 1 . The disruption of equilibrium in tooth position may be caused by several etiologic factors. These include pressure from inflamed tissues, periodontal attachment loss, occlusal factors, loss of teeth without replacement oral h...

BACKGROUND Alveolar ridge resorption, as a significant problem in implant and restorative dentistry, has long been considered as an inevitable outcome following tooth extraction. Recently, adrenomedullin (ADM) is reported to be able to stimulate the proliferation and migration of various cells including osteoblasts. The purpose of this study was to investigate the influence of local ADM applica...

The utility of stable oxygen isotope analysis for demonstrating human migration has been developed and demonstrated on archaeological human populations. The application of this approach to tracking human movement has seldom been applied within forensic science. This paper gives results from a stable oxygen isotope assessment of extant modern human and horse enamel 18O values recovered from toot...

Objectives: The aim of this study was to investigate whether altering the labial-lingual position of lower incisors in adolescents might predispose to the development of gingival recession. Methods: Records from 189 Caucasian adolescents (107 female and 81 male) pre and post orthodontic treatment were selected. Patients yielded mean ± SD values of initial records age 11.2 ± 1.9 years and final ...

Ectodermal contribution to the induction of pharyngeal teeth that form in the endodermal territory of the oropharyngeal cavity in some teleost fishes has been a matter of considerable debate. To determine the role of ectodermal cell signaling in scale and tooth formation and thereby to gain insights in evolutionary origin of teeth, we analyzed scales and teeth in rs-3 medaka mutants characteriz...

The migration of packaging material constituents into food is a product of the interaction between the food and packaging material. This phenomenon is of importance because some migrating substances may be toxicologically carcinogenic and endanger the consumer safety. Polystyrenes are used in many food-contact applications for the packaging of aqueous-based, fatty and dry foods. The correlation...

treatment method for dental Class II pa ­ tients with excessive overjet, anterior crowding, or both. Given the unpopularity of headgear among pa tients,1,2 clinicians increasingly prefer intraoral appliances with minimal need for patient coop­ eration. Unfortunately, most of the conventional non­compliance devices produce unwanted side effects. Anchorage loss of 24­55% can result in mesial migr...
